Tips for improving your vehicle’s fuel efficiency and reducing its environmental impact, including advice on driving habits, maintenance practices, and choosing the right tires.

1. Keep your tires properly inflated. Underinflated tires can decrease fuel efficiency by up to 3%.
   
   Properly inflated tires can improve fuel efficiency by reducing rolling resistance, which means the engine has to work less hard to move the vehicle. To maintain proper tire pressure, check the pressure regularly using a tire pressure gauge and add air as needed to reach the recommended level. The recommended tire pressure can be found in the owner’s manual or on the tire placard located on the driver’s side doorjamb or in the glove compartment. Do not overinflate the tires, as this can cause them to wear unevenly and reduce their lifespan.
   
2. Use the recommended grade of motor oil. Using a higher viscosity oil can increase fuel consumption.
   The viscosity, or thickness, of motor oil can impact the fuel efficiency of a vehicle. Using a motor oil with the wrong viscosity can increase fuel consumption and reduce the life of the engine. To ensure the best fuel efficiency, use a motor oil with the recommended viscosity for your vehicle as specified in the owner’s manual, and choose a motor oil that is labeled as “energy conserving” or “fuel efficient.” This will help improve the fuel efficiency of your vehicle and extend the life of the engine.
3. Reduce the weight of your vehicle by removing unnecessary items.
4. Use cruise control on the highway. Maintaining a constant speed can improve fuel efficiency.
5. Avoid rapid acceleration and braking. These actions can increase fuel consumption.
6. Avoid idling for long periods of time. Turning off the engine can save fuel.
7. Use your vehicle’s overdrive gears. These gears can reduce engine speed and improve fuel efficiency.
8. Use a fuel-efficient driving style. Anticipating stops and taking corners slowly can improve fuel efficiency.
9. Use the appropriate octane fuel for your vehicle. Using a higher octane fuel than recommended can decrease fuel efficiency.
10. Keep your vehicle well-maintained. A poorly tuned engine can decrease fuel efficiency.

By following these tips, you can help improve the fuel efficiency of your vehicle and save money on gas.
